I have 3 different TRU Arceus, GAMESTP Pichu, GAMESTP Jirachi, Aura Mew, TRU Shaymin, 10 ANIV Celebi, an SS Groudon (not really an event but unlocks rayquaza if you also have a HG Kyogre), I also have every legendary and normal pokemon caught from various games. I have not calculated any of their IV's though.
